Welcome on the homepage of the chair "Computer Graphics Systems" of Prof. Jürgen Döllner and his team. We like to inform you about our teaching and ongoing research activities in the analysis, planning and construction of computer graphics and multimedia systems.

3D Annotation Technology

The 3D annotation Technology enables to enrich 3D virtual environments with external and embedded annotations of static and dynamic content. The technology is available as a independent library component.

Annotations are vital elements for the comprehension of virtual environments. The optimal placement with respect to the 3D scene and the annotation content is a hard computational problem.

3D Smart Interaction Technology

Smart interaction technologies leverage object semantics of a virtual scene to support the control of the virtual camera and thus eases the navigation for the users. This includes the application of gestures.

Such smart interaction techniques avoid “getting lost” situations within complex virtual 3D environments and has various applications: from modern mobile devices to tourist information systems.

3D Automated Texturing Technology

Given the 3D geometry of a virtual city model and a set of oblique images of the same geographic region, this technology generates building façade and roof textures in a fully automatic way, using consumer graphics hardware.

It enables photo-texture generation for complete virtual 2D city models and represents the basis basis for derivation of non-photorealistic textures or textures encoding surface feature properties of buildings.

Collaboration Tools for 3D City Models

This technology enables communication of spatial information using 3D geovirtual environments. Same-time and time-shifted work processes can be supported by communication tools.

It is suitable for retaining the spatial reference of information over time (e.g., for public participation scenarios, communication purposes).

3D Focus-&-Context Technology

This interactive technique uses generalized clipping to combine different geometric representations (e.g., levels-of-abstraction) within a single image. It can be used to implement focus+context visualizations using 3D lenses.
